Threat Database Trojans Trojan:JS/BlacoleRef.CZ


By Domesticus in Trojans

Trojan:JS/BlacoleRef.CZ is a JavaScript Trojan that is added into hacked websites. A hijacked website may permit a cybercriminal to successfully embed a client-side script, which then runs when an Internet user visits the hijacked website. Trojan:JS/BlacoleRef.CZ is generated to load a hidden IFrame that loads behind the attacked computer user's web browser, rerouting it to an exploit server known as 'Blackhole'. The payload of Trojan:JS/BlacoleRef.CZ may be different, based on what the reference host delivers at the time of compromise. The combination of obfuscated JavaScript within a hidden IFrame, which references a malevolent host, and the malevolent host itself, which is responsible for dynamically generated content, which aims at exploiting numerous vulnerabilities on the target computer user's PC, are monitored and could be changed by a cybercriminal at any time. The reference host is responsible for loading the main exploit code of 'Blackhole', which attacks the PC by executing numerous known and 'zero day' vulnerabilities through the hacked web browser.
